WINDING DEVICE.

Application filed April 2,

Be it known that I, MAX Or'ro CLAUSS, a citizen ofthe United States, andresident of the borough and county of the Bronx, city and State of NewYork, have invented certain new and usefulImprovements in VindingDevices, of'which the following is a specification. V Y

The present invention rclatesto improvements in winding devices,particularly for winding yarns or other threads into'balls, and has foran object to provide in such a device improved tension means by means ofI which the winding may be carried on in a uniform and reliable manner.

Heretofore, the tension means employed in such devices causedvariation'in the ten sion, with the result that the winding Was notuniform, and there was constant danger of the thread breaking,necessitating stopping of the work, much delay and great waste. Alsotheuneventension frequently caused the balls being wound to fly offofthe ball spindles. In the present device, I propose to obviate thesedisadvantages, to the end that a uniform winding results, and the devicemay be. operated with greater efliciency as to time, labor and material.

A further object is to provide improved means for accurately adjustingthe tension.

With these and other objects in view, embodiments of my invention areshown in the accompanying drawings, and these embodiments will behereinafter more fully described with reference thereto, and theinvention will be finally pointed out in the claims.

In the accompanying drawings;

Figure 1 is a side view of an embodiment of my invention;

Figure 2 is a front view of the same;

Figure 3'is a plan'view thereof;

Figure 1 is a plan view of a. slightly modified form of tension means;

Figure 5 is a side viewthereof;

Figure 6 is a sectional view taken along the line 6-6 of Figure 4:;

Figure 7 is a side view of a further modified form of tension means; and

Figure 8 is a plan view thereof.

Similar reference characters indicate corresponding parts throughout theseveral figures of the drawings.

Referring to the drawings, and more particularly to Figures 1 to 3thereof, the embodiment of my invention shown therein I Specification ofLetters Patent; Patented 1131', 14, 1922,

1918. Serial No. 226,173.

comprises a shaft 10 rotatable in the direction of the arrow, andprovided with a thread guide passage 11 therethrough, through which thethread passes from an eyelet 11 and a core 11 or other source of supply.Upon the end of the shaft 10 there is secured a face plate 12 having apassage 13 therein, continuous with the passage 11, the said plateextending considerably below the shaft to form a counterweight as at 14,and provided upon its short end with a flier arm 15, projectingforwardly in an up wardly inclined direction.

The end of the arm 15 is bent downwardly as at 16, and is provided witha cut out 1? forming a flat bearing surface, a thread passage 18extending from one end wall of said out out to the end of the arm, andanother thread guide passage 19 extending from the other end walldiagonally through the arm to the underside thereof. The thread to bewound passes from the passage 12, 13 to the passage 19 across the outout 17, and through the passage 18 to the inclined ball spindle 20,which rotates intermittently in the direction of the arrow, the verticalplane of rotation of the thread passing diagonally through the saidshaft. The thread is there by wound into a ball upon the shaft 20.

Upon the upper side of the flier arm there is provided a leaf spring 21,having downwardly turned lugs 22 and 23 pivoted at 24 to the arm, theforward up-turned end 25 thereof pressing upon the thread as it movesover the bearing surfaces 17, while the other end is engaged at theunderside by the peak 26 of an adjustable set screw 27 provided in thearm. Uniform tension is thereby produced upon the thread, and this maybe accurately adjusted by the set screw, a scale 27 and index 27 beingprovided to indicate the amount of tension. By having the tension meansor the end of the flier arm at a considerable distance from the supplycore 11*,

trifugal throw of the weight causes the tension to be increased ordiminished upon the thread. Thus the adjustment may be very accuratelymade to suit the particular thread wound. The portions 29 and 30 ex- 7tending over the top of the arm are preferbein ably spring-like so as totightly grip the arm during rotation of the flier arm, but at the sametime permit the same being adjusted manually; Other fastening means maybe provided if desired.

In Figures 7 and 8, I have illustrated a still further form of tensionmeans, consisting of a forked or slotted member 31 rotatably securedupon the side plate 32 by means of a set screw 33. The thread is carriedthrough the fork, and by adjusting the fork the functional tension maybe increased or diminished as desired. Ascale 34 and index 35 areprovided to indicate the tension according to predetermined standards.

I have illustrated preferred and satisfactory embodiments of myinvention, but it is obvious that changes may be made therein within thespirit and scope thereof, as def fined in the appended claims.

I Ijclaim e 1. In a thread winding device, a flier'consistingof a flierarm, thread guiding means thereon at the end thereof for guiding thethread longitudinally of said flier arm and in a patl1 that is a single,simple curve from i the point at which the thread enters the -threadlongitudinally of the arm as it passes over such bearing surface, aguide passage at one end of the bearing surface for the incoming thread,a guide passage at the other and outermost end of the bearing 'surfacefor outgoing thread, the thread passing through the incoming guidepassage over the bearing surface and through the outgoing guide passagein a generally curved path, the'path being a single, simple curve, andan adjustable tension device adapted to create tension onthe threadpassing over the bearing surface at a point adjacent the outgoinpassage.

3. n a thread winding device, the com;

ing the thread in a single continuous unidirectional passage thatfollows a generally simple curve, the exit of vthe passage being over.the end of the flier arm, the passage being only'longitudinally of thearm, and

thread tension means on said flier arm acting on the threadwhile itpasses over the flier arm and near the outlet end of said thread as itleaves the flier arm, :the end of the flier arm adapted to rotate inspaced relation about the ball formed on the ballingspindle by thethread under the tension of the tension device on the flier arm.

4. In a winding device, a rotating flier, means to receive the windingthread axially of thecenterof rotationof theflier and to lead the threadWithin thecircle of rotation of the flier, said flier having threadpassages near its free end, thevvinding thread being received throughone of the passages to the outside of the flier after passing freely anduninterruptedly from the point of its axial exit, the thread being ledinwardly from the other passage at the extremity of the flieri to aballing spindle, and means upon the threadas it passes between thepassages for creating tension near the outer part of the flier and nearthe'balling spindle.

5. In a winding device, a rotating shaft having a thread guidetherethrough adapted to receive a'winding thread froma source of supply,the thread guide passing axially throughtheshaft, a flier arm mounted onsaid shaft and turning axially with the thread passage, said arm beingelongated and extending diagonally from the shaft and having a pairofclosely assembled thread passages near its outer free end, said outerfree end being curved inwardly toward the axis of rotation of the flierarm, the thread from the thread guide passing axially with-:

in the circle of rotation of the flierarmand extending directly to theinitial thread'passage in the arm, said initial thread passage beingcurved outwardly and toward the bend given the free end of thefl'ierarm, the winding thread extending in a curved path from its point ofentrance to the receiving passage to the point of exit from the'otherthread passage of the arm, said flier arm having a flat surface betweenthe two thread passages,

and adjustable friction means bearing upon. the thread-upon this flatsurface to create tension thereon just prior to the thread leaving theflier arm; 7 r

In testimony that I claim the foregoing as my invention, I have signedmy name.
